Attackers can craft GGUF files with enormous tensor extents that overflow ggml_nbytes() and strides, causing out-of-bounds memory access when buffers are sized from wrapped byte counts.","categories":["Unclassified"],"product":"llama.cpp","vendor":"ggml-org","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116829","source_modified_at":"2026-10-27T00:33:59.223Z","fetched_at":"2026-10-27T04:51:10.072820Z","product":"llama.cpp","vendor":"ggml-org","versions":[{"version":"b10398","status":"affected","versionType":"custom","lessThan":"b11301"},{"version":"0.1.0","status":"affected","versionType":"semver","lessThan":"0.6.0"}],"defaultStatus":"unaffected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-116829","source_modified_at":"2026-10-27T00:33:59.223Z","fetched_at":"2026-10-27T04:51:10.072820Z","package":{"name":"llama.cpp","ecosystem":null},"version":"0.6.0","basis":"first unaffected version stated in the CVE record"}],"cvss":6.9,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T00:33:59.223Z","modified_at":"2026-10-27T00:33:59.223Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-116829","fetched_at":"2026-10-27T04:51:10.072820Z","source_modified_at":"2026-10-27T00:33:59.223Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/ggml-org/llama.cpp/issues/29383","tags":["issue-tracking"]},{"source":"CVE List","url":"https://github.com/ggml-org/llama.cpp/pull/29384","tags":["patch","issue-tracking"]},{"source":"CVE List","url":"https://github.com/ggml-org/llama.cpp/commit/2149c00f4442dc59302e134a02e4c99d5f7ed9fc","tags":["patch"]},{"source":"CVE List","url":"https://github.com/ggml-org/llama.cpp/blob/v0.5.0/ggml/src/gguf.cpp#L701","tags":["technical-description"]},{"source":"CVE List","url":"https://github.com/ggml-org/llama.cpp/releases/tag/b11301","tags":["release-notes"]},{"source":"CVE List","url":"https://www.vulncheck.com/advisories/llama-cpp-b10398-before-b11301-integer-overflow-in-gguf-init-from-reader","tags":["third-party-advisory"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T00:33:59.223Z","content_hash":"3a2c7276abae2dba1d38f065fb133499e14b2647a0991050b3a36f53143da229"}}
